Solve using the order of operations. (9+9+72)-4+9

PLZ ANSWER PLZ HURRY​

Answers

Answer 1

Answer:

95

Step-by-step explanation:

The order of operations is PEMDAS

Equations in PARENTHESES come first

Numbers with EXPONENTS come second

MULTIPLICATION/DIVISION problems come next (depending on which comes first in the equation

ADDITION/SUBTRACTION comes last (again, depending on which comes first in the equation)

So we do (9+9+72) first

So that equals 90

And then we subtract 4 from 90

90 - 4 = 86

Then we add 9 to 86

86 + 9 = 95

Answer 2

Answer: 72 is the answer

By virtue of the Pythagorean Theorem, in a right triangle the sum of the squares of the smaller two sides equals the square of the largest side. Only 9, 12, and 15 fit this rule.

There are cows and turkeys at a farm, 82 heads and 264 legs in all. There is no need to explain that a cow has four legs, while a turkey has two legs. How many cows and turkeys are at the farm? How can I solve this using elimination or substitution can I have steps please. No spamming please

Answers

Cows have 4 legs and turkeys have 2 legs. They each only have one head.
Cows+turkeys=82
4 cow legs + 2 turkey legs = 264
C+T=82
-T. -T
—————
C= 82-T wherever you see a “C” substitute this formula

4C+ 2T=264
4(82-T)+ 2T=264
(82*4)- (4T+2T)= 264

328-2T=264
-328. -328
————————
-2T= -64

-2T/-2= -64/ -2

T=32 there are 32 turkeys
There are 82 heads total
If we know there are 32 turkeys then the rest have to be cows.
82-32=50

Find the area of the composite figure?


Answers

Answer:

128

Step-by-step explanation:

Let's start by figuring out the last side of the triangle

we can use the pathagoryous theroem and get

11.9²+x²=16.9²

Solve this and get x=12

Let's now compute the area of the triangle

b*h*.5

12*11.9*.5=71.4

So 71.4 is the area of the triangle

we now need to find the area of the semi circle.

to do this we are going to find the area and then divide it by 2

We know that the length is equal to 12 which means that the radius is 6

so we have

π6²/2

which is 56.55

We add the 71.4+56.55= 127.94 which rounds to 128

Answer:

212.758

Step-by-step explanation:

Find the semi-circle first, the diameter is 16.9 ft.

To find area:

Formula:

pi x radius x radius x 1/2

16.9 ÷ 2 = 8.45 (radius)

22/7 x 8.45 x 8.45 = 224.407 (Circle)

224.407 ÷ 2 = 112.203 (Semi circle)

Find the triangle:

1/2 x base x height or length x base x height

But for now, we will use the first one.

1/2 x 16.9 x 11.9 = 100.555

Now add them up.

100.555 + 112.203 = 212.758

Answers

$4.50

Hope this helps!

Answer:

$20.50

Step-by-step explanation:

100% price - 18% discount = 82%.

82% can be written as .82

The original price was 25, so we multiply 25 by 0.82. We get $20.50.

If you are looking for the amount saved, subtract 20.5 from 25. We get $4.50.

Identify whether the expressions are equivalent or not equivalent: 7y – 15 + 2y and 9y - 15

Answers

Answer:

Yes, the two expressions are equivalent

The given expression 7y - 15 + 2y and   9y - 15 are equivalent.  

What is equivalent expression?

Two algebraic expressions are said to be equivalent if their values obtained by substituting the values of the variables are same, even they look different.

According to the given question.

We have two expressions

[tex]7y - 15 + 2y ...(i)[/tex]

And, [tex]9y - 15 ...(ii)[/tex]

The expression (i) can be written as

[tex]7y - 15 + 2y[/tex]

[tex]=(7y + 2y)-15[/tex]            (adding the like terms)

[tex]= 9y -15[/tex]    

Hence, the given expression 7y - 15 + 2y and   9y - 15 are equivalent.

A farmer wants to fence a piece of his land. Two sides of the triangular field have lengths of 120 feet and 325 feet. The measure of the angle between those sides is 70 degrees. How much fencing will a farmer need?

Answers

Answer: Area=18324 square feet

Explanation: We need to find the area of the field using the side angle side method, which uses the equation (ab*sin C)/2.
Thus, we have (120*325*sin 70)/2=18324 square feet.

Farmer need 750.5 feet fencing for his triangular field.

What is triangle?

"Triangle is  two dimensional geometrical shape with three sides and three vertices. Sum of all the angles of a triangle is equals to 180°.

Formula used

Cosine rule

As per the diagram,

cosθ = (b² +c² -a²) / 2bc

cos 70° = 0.3420

According to the question,

Let AB = c , AC = b  are given sides of measure 120 feet and 325 feet respectively.

and BC = a

Angle between given sides be θ = 70°

Substitute the value in the formula we get,

cos70° = [ (325)² +(120)² - a²] / 2(120)(325)

⇒ 0.3420 = [ 120025 - a²] / 78000

⇒ 120025 -a² = 26676

⇒ a² = 93349

⇒ a = 305.5

Total fencing required for  triangular field = AB + BC +CA

                                                                      = 120 + 325 + 305.5

                                                                      = 750.5 feet

Hence, farmer need 750.5 feet fencing for his triangular field.
